This Station is currently going under extensive rehabilitation, including the instalation of ADA elevators (for exact details, this link is on info from the MTA's Webstie) this summery is of the station before it began going under reconstruction in 2009.As of June 2011: Manhattan-bound trains are stopping only on the express track (and bypassing Avenues M and H), and a temperary platform has been set up over the Coney Island-bound express track and trains are using that platform which is the only one open. One fascinating revealed piece of signage is visible on the Manhattan-bound platform are old D to 205, The Bronx via 6 Av Express, all times. This was the service before 2000, what has probably happened is old signboards that covered the existing ones have been removed.
The Kings Highway Station is a Brighton Line Express stop with two island platforms for the four-track line. It was given a bit of a renovation in the late 1980s and has some unusual features, like bricks along all the platform staircases that lead down below, and lampposts that aren't standard at the extreme ends of both fairly narrow platforms where their not canopied. The station in general has three main exits, starting from the southern end of the station there is a pair of staircases that lead down from each platform to the full-time exit, located at street level beneath the tracks that has a long bank of turnstiles that than in turn lead to sets of doors on the southern sidewalk of the main Kings Highway shopping district as it crosses beneath the subway tracks. From the staircases down from the Brighton/Coney Island-bound platform there is a separate High Exit Turnstile that allows exiting passengers to skip entering the main fare control area and exit directly to the street. Continuing northword, the next station entrance is on the north side of Kings Highway beneath the subway tracks, here three High Entrance/Exit Turnstiles are nestled directly along the street. There is also an MVM, alongside them right on the street. There are no doors of any kind to enter the subway system from here and a staircase leads up to each platform. The final station entrance is across from when an eastern section of Quentin Road ends in a T-junction with East 16 Street. This subway entrance is also looks like a storefront, complete with an awning of old school cut outs of letters forming Subway. This subway entrance is open full time with a token booth and turnstiles open during the week, during the midnight hours and on weekends there's a High Entrance Turnstile for passengers to use. To reach the tracks from this entrance there is a passageway that turns 90 degrees before staircases up to either platform. At the northern end above the station is a decently sized non-public MTA building nestled above the four tracks and two platforms.
